Tough, simple and cost-effective starting for diesel engines

1 When Power is Critical Tough, simple and cost-effective starting for diesel engines For diesel engines up to 18 litres IPU s spring starter motors are a reliable and costeffective way of providing manual starting for diesel engines. They deliver reliability through simplicity. To start an engine you simply engage the start motor, wind the handle until a coloured indicator shows the motor is fully charged and remove the winding handle. Then pull on the trip lever and the starter motor will turn the engine. It s that simple! IPU spring starters are perfect for harsh environments such as offshore and marine applications as they are unaffected by temperature extremes and damp conditions. Simple Spring starters require no electricity, no air pressure or hydraulic fluid. It is a simple alternative or back-up start system for most applications. Cost-Effective Spring starters are a direct bolt-on alternative to electric starters providing quick and easy installation. Tough They are resistant to damp and extremes of temperature making them an ideal choice for offshore and marine environments.

2 Spring Starter Applications Applications There are many different applications for spring starters, including: Where simplicity, robustness and reliability are essential and the apparent convenience of push-button starting is less important For environments such as mines and oil refineries where electrical equipment can be illegal or dangerous Where problematic conditions such as vibration, heat, dust, salt water need to be overcome In remote locations or where poor operational skills mean simplicity is more important than sophistication For emergency and strategic use such as on lifeboats or with military, emergency or backup generators An IPU spring starter can be used on any direct injection diesel engine between 0.5 and 18 litre capacity with sufficient space to accommodate the starter. Spring starters are ideal for many applications: Boats Tractors Grain mills Pumps Generator sets and compressors Dump trucks Fork lifts Construction equipment Hydraulic power units Winches Welders Drilling equipment IPU s Spring starters are suitable for numerous engines: Deutz Farymann Hatz Lister Lombardini Kubota Perkins Ruggerini Caterpillar Cummins Detroit Man Perkins Scania Volvo Customer Benefits Guaranteed starting: manual operation makes cranking unaffected by long shutdowns, damp, cold or harsh environments. Reliability: many spring starters are still operating after decades in service. Space and weight saving: the smallest spring starters are only 12kg, less than 50% the weight of a conventional electric starter. Operator safety: the crank will not kick back during operation and the motor can be unwound. Ease of use: spring starters are a direct bolt-on alternative to electric starters. Reduces battery costs: for certain applications, such as pumps, welders and gen-sets you can remove the need for a battery completely. Lower electrical equipment costs: with no electric starter a lighter duty alternator can be fitted.

3 Additional Information Anti-Clockwise Spring Starter Although niche, there is a clear demand for anti-clockwise rotation starters. The need is especially strong where engines do not have a second pocket for a backup starter or where there is insufficient space on the engine to mount a second starter. Once engine companies developed flywheel housings with an extra pocket for a backup starters (especially common with lifeboat engines) the opportunity was there to develop anti-clockwise mechanical starters. The mini, midi, heavy duty midi, maxi and super maxi spring starters are available in clockwise and anti-clockwise format. How long can a spring starter be left fully-charged? It is anticipated that a spring starter can be left fully-charged for up to one year without any noticeable energy loss. If the starter motor is designed to be a secondary start system it should not be left fully-charged. How many revolutions of the flywheel will I get with an IPU Spring Starter? That depends on the size of the engine. As a rule of thumb, a six litre multi-cylinder engine will turn through 1.5 to 2.5 revolutions and a small single or multi-cylinder engine with capacity of 0.7 to 1.5 litres will turn through 5 to 8 revolutions. How does an engine start with so few revolutions? On a small engine the IPU Spring Starter rotates the engine through almost the same number of revolutions as an average electric starter but at approximately three times the speed. On larger engines it rotates the engine approximately twice as fast as an electric starter, allowing much less time for the heat to dissipate through the cylinder walls during a compression stroke. This helps the engine cylinder rapidly reach its ignition point.

4 Spring Starter Product Range Mini Spring Starter The Mini Spring Starter is our smallest and lightest starter weighing a modest 12 kg (26.5 lb). The Mini Spring Starter is suitable for diesel engines from 0.5 to 2.5 litres (30.5 to cubic inches) and is available as a clockwise and anti-clockwise model. The Mini Spring Starter is the first of its kind in the world. It brings non-electric backup starting to smaller engines, bringing with it all the reliability benefits of mechanical starters. The Mini Spring Starter is used for life boat engines, portable fuel pumps and water pumps in remote locations. Midi Spring Starter The Midi Spring Starter is suitable for diesel engines from 1.1 to 6.6 litres (67.1 to cubic inches) and is available as a clockwise and anti-clockwise rotation model. The Midi Spring Starter is the first mechanical starter to have a two piece mounting bracket which means this starter is easy to convert to another model just by replacing part of the mounting bracket (mounting flange). This makes the Midi Spring Starter an efficient and economical unit. Heavy Duty Midi Spring Starter The Heavy Duty Midi Spring Starter is suitable for diesel engines up to 7.8 litres (476 cubic inches) and is available as a clockwise and anti-clockwise model. The Heavy Duty Midi Spring Starter serves engines which have a slightly larger capacity than the standard Midi starter can handle or engines that need low temperature starting.

5 Spring Starter Product Range Maxi Spring Starter The Maxi Spring Starter is suitable for diesel engines up to 10 litres (610.2 cubic inches) and is available as a clockwise and anti-clockwise model. The Maxi Spring Starter is the first manually operated starter in the world to be able to start diesel engines over 8 litres (488.2 cubic inches) capacity. Compared to other non -electric starting systems, the Maxi Spring Starter is by far the most economical option. It competes with electrical starting systems and as a result has drawn custom from a large number of shipping companies all over the world. Heavy Duty Maxi Spring Starter The Heavy Duty Maxi Spring Starter is suitable for diesel engines up to 15 litres (915.4 cubic inches). It is available as a clockwise rotation model only. The Heavy Duty Maxi Spring Starter was developed following the success of the Maxi Spring Starter range. Some of the components were redesigned and the patented multi-rate spring pack transformed the Maxi Spring Starter into a new Heavy Duty Maxi Spring Starter. Super Maxi Spring Starter The Super Maxi Spring Starter is suitable for diesel engines up to 18 litres ( cubic inches) and is available as a clockwise and anti-clockwise model. The Super Maxi Spring Starter is the first manually operated starter in the world to be able to start 18 litre diesel engines, a feat considered impossible until its launch. It provides ship builders with an easily-installed starter range they can offer in their vessels to provide reliable starting for engines and emergency generators.
